This Blue Lagoon Mocktail, made with blue curacao syrup, fresh lemonade, and a sparkling soda, is a sweet and citrusy Caribbean-sea-colored drink the whole family can dive into! Perfect for essentially any occasion!
What could be better than this blue lagoon mocktail if you’re looking for a party-pleasing punch in a brilliant shade of blue?! This mocktail-making guide includes everything you need to make the best non-alcoholic version of the classic-mid-century mixed drink known as the “blue lagoon.” So let’s jump right in!
What Is A Blue Lagoon?
The blue lagoon became a famous cocktail on big-city bar menus in the early 70s, not long after blue curacao liqueur was introduced. The most basic blue lagoon recipe is a vodka lemonade base with a splash of blue curacao.
Blue curacao is an orange-flavored liqueur (aka triple sec) dyed blue. It’s responsible for the beautiful blue hue and bringing a very sweet clementine and orange essence to the blue lagoon drink.
That said, blue curacao liqueur does indeed contain alcohol, but not all blue curacao is alcoholic. The alcohol-free version is relatively easy to source for this blue lagoon mocktail, but if you can’t find it, it’s also pretty simple to make with orange-flavored simple syrup with blue food coloring.
The remaining blue lagoon mocktail includes a mixture of lemonade, sparkling water, and freshly squeezed lemon juice. You can sit back, relax, and enjoy this sweet, tart, and tangy drink, or make a big batch for a theme party.
Why You'll Love This Recipe
- It takes under 5 minutes to make with four no-fuss ingredients plus the glass garnishes. No fancy bar equipment is needed.
- This blue mocktail is perfect for pool parties, baby showers, Fourth of July gatherings, under-the-sea & beach-themed parties, and so on.
- This is a no-alcohol family-friendly version of a classic cocktail so everyone can enjoy it.
- It’s easy to revert to the cocktail version if you want something extra.
Ingredients You'll Need
- Blue curacao syrup – I recommend Monin blue curacao syrup (you can find it on Amazon). It’s made with minimal ingredients, including pure cane sugar and natural flavors, and tastes very similar to blue curacao liqueur. Of course, you can use the liqueur to upgrade this mocktail to a low-alcohol cocktail.
- Lemon juice – Freshly squeezed, please! Worst case, you can use lemon juice from concentrate, but fresh juice from a good lemon impacts the final flavor significantly.
- Lemonade – I like Simply Lite lemonade, but you can also use a zero-sugar lemonade to reduce the sugar and calorie content.
- Sparkling water – For the carbonated bubbles! Use pure sparkling water or switch things up with a fun sparkling water flavor. To make a sweeter drink, use sugar-free lemon-lime soda instead of sparkling water here.
- Garnishes – For a true blue lagoon experience, garnish your glass with a lemon wheel, pineapple slice, and a maraschino cherry on top! Cocktail umbrella optional.
How To Make A Blue Lagoon Mocktail
Step 1: Shake mocktail ingredients. Add a scoop of ice to a cocktail shaker or mason jar with a tight lid. Add the blue curacao syrup, freshly squeezed lemon juice, and lemonade, and shake vigorously for 10 seconds or until frosty.
Step 2: Pour over ice. Fill a tall glass with fresh ice and strain the blue lagoon mocktail mixture over the top.
Step 3: Top with soda and stir. Fill the rest of the glass with zero-sugar lemon-lime soda, sparkling water, or a fun seltzer water flavor. Keep reading for ideas!
Step 4: Garnish glassware and serve. Garnish the glass with lemon, pineapple, and a maraschino cherry, and enjoy!
- If you cannot find non-alcoholic blue curacao syrup, you can make it by adding blue food coloring to orange-infused simple syrup. OR, you can use clear orange simple syrup instead of blue curacao syrup and then add 2-3 drops of blue food coloring directly to your drink.
- You have a few options to beat the heat and a watered-down drink. First, you can make an extra blue lagoon to freeze into cubes and then use the cubes to chill your future fruity mocktails and mixed drinks.
- Making the drink with pre-chilled ingredients, chilling the drink itself before serving, chilling the glass itself before using it, and using large ice cubes are good tactics to keep your mocktail cold longer in the hot summer heat.
Flavored sparkling water – Instead of pure sparkling water, put your mixologist skills to the test and experiment with fun LaCroix sparkling water flavors. For example, try lemon, orange, peach-pear, pineapple guava, coconut, etc.
Lemon-lime soda option – Another option is replacing the lemonade and the sparking water with lemon-lime soda. I love making this drink with zero-sugar Sprite and a splash of freshly squeezed lemon juice instead of lemonade and sparkling water.
For a tropical twist – Enhance your mocktail with a splash of pineapple juice, keeping in mind that with pineapple juice, your blue lagoon will be more like a sea-green lagoon.
This Blue Lagoon mocktail is best enjoyed right after mixing, or the sparking water will start to lose its fizz, causing the drink to fall flat.
However, If you made too much, you can freeze the liquid in an ice cube tray, transfer the cubes to a freezer bag, and keep the bag stashed in the freezer for up to a month. So the next time you’re craving a blue lagoon, you’ll have a stash of pristine blue lagoon frozen cubes that won’t dilute your mocktail as they melt.
Frozen blue lagoon mocktails are absolutely an option. Simply add the ingredients to a high-speed blender with 1⁄2 - 1 teaspoon of xanthan gum to help thicken it.
If you want to make a classic blue lagoon, that’s easy! Mix lemonade with blue curacao liqueur instead of syrup and 1½ - 2 ounces of vodka. If you don’t like vodka drinks, white rum, coconut rum, or silver tequila will also bind smoothly with lemonade and blue curacao drinks.
